REFRIGERATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 493,120, dated March 7,1893. y

Application filed November 7, 1890. Serial No. 370.677. (No model.) l

To all whom it may concern:

Be it known that I, JOSEPH SOHEUEEECKER, of Toledo, county of Lucas, andState ot' Ohio, have invented certain new and useful Improvements in anApparatus for the Manu-v facture of Ice and for Refrigerating Purposes;and I do hereby declare that the following is a full, clear, and exactdescription of the invention, which will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to the figures of reference markedthereon, which form part of this specification.

My invention relates to an apparatus for the manufacture of ice and forrefrigerating purposes, and has for its object to provide a compact andcomparatively inexpensive apparatus' for this purpose that can beadapted for domestic or commercial use.

` A further object is to provide an apparatus especially adapted for theuse of aqua ammonia as a cooling agent, with means for inducing acirculation of the cooling medium, Without the use of pumps.

A further object is to store the anhydrous ammonia Within a reservoirfrom which it may be led to a place of use, either for `manufacturingice, or for refrigerating purposes.

A further object is to economize in fuel in liberating the ammoniavapor.

A further object is to combine in one apparatus an ammonia receiver, areservoir for anhydrous ammonia,` a furnace for expelling the ammoniagas, and a cooling chamber, thereby simplifying and cheapening theconstruction. Y

The invention consists in the parts and cornbination of partshereinafter described and pointed out in the claims.

Y In the drawings, Figure 1, is a longitudlnal vertical section of anapparatus, constructed in accordance with my invention, with a freezerfor manufacturing ice attached thereto, and showing a pipe for leadingto any receptacle wherein refrigeration 1s ueslred: Flg. 2, is alongitudinal vertical sectional view of the receptacle for gaseousammonia. Fig. 3, is a horizontal section on lines :1c-cc, Fig. 2.y

Fig. 4, is a horizontal section on lines y-fg, Fig. 2. Figo, is a bottomplan view of the valve for controlling the flow of ammoniacal gas.

Having stated the 'objects and described the figures employed toillustrate the means for carrying out-these objects,I will now proguresof reference indicating corresponding parts. Y

1 designates a jacket in which is arranged a portion of the ammoniastill 2, which being `of less diameter than the jacket, forms an annularchamber 3, surrounding the still, there being a furnace-grate 4, locateddirectly beneath the bottom of the still, wherebyithe product ofcombustion entirely surrounds the is formed an annular seat 6, for anannular closure 7, suspended upon rods 8, which pass "through the top ofchamber 3 and serve to elevate the closure when it is desired to renderthe chamber Water tight, or to be depressed when it is desired to heatthe still.

9, designates a metal vplate which serves as a top to the still and as abase to the water reservoir 10. Reservoir 10, comprises an outer casing11, and an inner receptacle 12, for containing the anhydrous ammonia,the still and reservoir being in communication through the medium ofpipe 13, which extends from the base 9 to the top of the reservoir andopens into the same at14, by means of an opening, closed when desiredby-avalve l5. The relative diameters of reservoir 10 and receptacle thereceptacle, thereby forming a water spacein communication with a watersupply pipe 16. Valve 15 is formed with a stem 17, extending through thetop of the reservoir, and being suitably packed by a stuffing-box 18,the lower enlarged portion 19, being seated in the chamber formed in thehead, and having an annular ring 20, depending from the head andperforated as'at 21, and 22 to register with the opening 14 and anopening 23, respectively, there being perforations 24 and 25 which areadapted to register with perforaceed to describe the apparatus indetail, like y same and finds exit .through flue or pipe 5.v At the baseof the annular chamber 3 there 12 are such that an annular spacesurrounds i tions or channels 26 and 27, respectively, formed in thehead, both being in communication with a pipe 28, leading to the bottomof the gas receiver, the former being in communication with a pipe 29,for leading the cooling fluid to the place of refrigeration, and thelatter being connected with a pipe 30, leading therefrom to the iceforming receptacle 31.

32, designates a pipe leading from the place of refrigeration and incommunication with a pipe 33, leading into the still, the lower coiledend 34, thereof being perforated to discharge the weak ammonia as it isreturned from the refrigerator or ice machine in its circulation fromthe reservoir into the still, whereby a constant flow thereof isinsured, pipe 35, leading from the ice machine and tapped into pipe 33,subserving the same purpose when the ice machine is in operation. Pipe36, is tapped into the cold water main and leads to the ice machine 31and discharges water upon the conical perforated diaphragm 37,arrangedacross the top of an inner chamber 38, surrounded by an outer casing 39,of a diameter to form an annular chamber 40. Between the casing 39 andthe wall of chamber 38 is arranged a spiral diaphragm 41, leading fromthe top to the bottom thereof, thereby forming a tortuous passage forthe cooling medium as it is discharged thereon through pipe 30, and ledtherefrom through pipe 35 back to the still.

42, designates an outer receptacle from which the chamber 38 and casing39 are suspended, the diameter of the outer receptacle is such as toVform an annular chamber 43, surrounding casing 39, the upper portion ofthe chamber being covered with a perforated diaphragm 44, and the entireice-forming receptacle as thus constructed is supported upon a hingedbracket 45, which is adapted to be swung beneath to sustain the same, orfrom beneath to allow of removal of the receptacle.

Frein the foregoing description the operation will be apparent. Asuitable quantity of aqua ammonia is introduced into the still throughan orifice 46, in the base plate 9, and the orifice closed by means of ascrew-plug 47. Closure 7 is lowered to allow the products of combustionto arise from a fire, which is now built upon grate bars 4. Valve 15 isturned to close communication of the reservoir 12 with pipes 29 and 30.i The aqua ammonia within the still is heated to a degree to cause rapidevaporation of the same, and the anhydrous gas flows up through pipe 13into the gas receiver until a sufficient pressure is maintained therein,(the fire in the furnace accomplishing this purpose in the space ofabout one hour,) when the valve is turned to admit the ammoniacal gas topipe 29. If to be used for refrigerating purposes, only the closure 7 israised to render the annular chamber 3 water tight and cold water isallowed to flow therein through pipe 48 and 48, as it is received fromthe water space in the reservoir water having been allowed to flowtherein to cool the gas, thereby lowering the temperature of the liquidwithin the still, and the ammoniacal gas flows in its return from therefrigerator through pipe 32 and into the still. If it is desired tomanufacture ice, the valve is turned to admit the cooling agent throughpipe 30 into chamber 40 and passes through the tortuous passage 41,thereby reducing the temperature in chamber 38 and 43 to a degree tocongeal the water as it is delivered thereto in minute jets or streamsthrough the perforated diaphragms 39 and 44 with the eifect of forming asolid body of ice within each chamber, when the bracket 45 is swung frombeneath the receptacle allowing the same to be removed to withdraw theice therefrom. It will be 0bserved that by allowing the water to jetthrough the perforations in the diaphragms into a temperature lower thanthe normal temperature of the water, the water is purged of air whichmay escape upwardly through the perforatons, thereby producing a clearcrystal ice as a product. It will also be seen that the cooling mediumcan be used for refrigerating purposes as delivered through pipe 29 atthe same time that it is used for the manufacture of ice through pipe30.

In Fig. l is shown in dotted linesa supplemental coil of pipe 50 adaptedto be opened to communicate with the reservoir for anhydrous ammonia,and deliver the same into the still to cool the contents where it isinconvenient to employ water for this purpose.

When it is desired to withdraw the water from reservoir lO, two-wayvalve 47 is turned permitting the Water to pass out of pipe 48, the pipe49 inchamber 3 subserving the same purpose.

My apparatus is of the compact form that it may be adapted to householduse 'for refrigeration, as its manipulation requires no skill, it onlybeing necessary to build a fire in the furnace when the flow of gas fromthe rcceiver has ceased, and the capacity of the receiver may be such asto only require this every twenty-four hours or even longer. It may alsobe increased in size and capacity to be adaptable to commercial use,either in a continuous supply to several consumers, or for manufacturingice in large or small quantities when it is desired.

What I claim is- 1. In an apparatus for the manufacture of ice and forrefrgerating purposes, a still, a jacket or shell surrounding the sameand forming an annular chamber, a furnace beneath the same, and amovable closure for opening or closing the annular chamber.

2. In an ice machine, the combination with the water tank, of an annularvessel arranged therein, said vessel being provided with a tortuouspassage to receive a cooling medium,
